Abstract
ABSTRACT The water policies adopt management instruments, among which the charge for water use stands out. Because there are many factors that can be used in an analysis of the efficiency of this management instrument in a watershed, it is necessary to use a scientific methodology for multi-criteria analysis. The aim of this study was to analyze the performance of charging for the use of raw water in the river basins of Ceará State in the main categories of use (industrial, supply and irrigation) using the methodology for data envelopment analysis (DEA) and the BBC model, with the help of computational tool SIAD (Integrated System for Decision Support) to designate the most and the least efficient units in order to improve the management of these resources. In this study, the industry units stood out, shwoing an average efficiency of 57.67%, followed by the public supply with an average efficiency of 22.69% and irrigation with an average efficiency of 11.78%. The charge for the use of water in the Litoral basin, in the industrial sector, stood out as the most efficient unit of the whole study, as the least efficient unit was the basin of the Litoral, in the irrigation sector.
Highlights
The charge for water use is provided for by law since the Decree 24643, of July 10th, 1934, known as the Water Code, which contained in its text current concepts such as user-payer and the polluter-payer principles
The analyzed decisions making units (DMUs) in this study present data with different sizes, as can be seen in Appendix A, they tend to have variable scales incomes
Because only 33 DMUs were proposed, it may be necessary to reduce the amount of factors
Summary
The charge for water use is provided for by law since the Decree 24643, of July 10th, 1934, known as the Water Code, which contained in its text current concepts such as user-payer and the polluter-payer principles. These concepts have not been put into practice. The charging for water instrument would only be formally established by Federal Law no 9433, of January 8th, 1997, popularly known as the Water Law. It is important to note that the State of Ceará was one of the states that anticipated the Union by establishing a policy of water resources, through the Law no 11996 of July 24th, 1992. According to Silveira, Forgiarini and Goldenfum (2009), the charge for the use of water resources still aims that this resource may be used in a rational way for its users, in order to meet the principles of the sustainable development
